POLYMERE OXYMETHYLENIQUE PERFECTIONNE ET SON PROCEDE DE PRODUCTION

摘要

Process and resultant product for controlling the spherulite size of crystalline oxymethylene polymers. Control over the spherulite size is achieved by incorporating into the oxymethylene polymer a polyalkylene terephthalate. Additionally, the incorporation of the polyalkylene terephthalate into oxymethylene polymers improves the color stability when exposed to heat and/or ultraviolet light of the oxymethylene polymers.
